What will be the final temperature of the system?

AI Thread Summary
The discussion revolves around a physics problem involving heat transfer between a hot iron chunk and ice. The key questions include determining the final temperature of the system, the initial temperatures of both the hot and cold iron, and the calculations based on given mass and specific heat values. Participants emphasize the need to apply thermodynamic principles, specifically the heat capacity and the heat required to melt ice. There is confusion regarding the number of iron pieces mentioned in the problem statement versus the questions posed. Assistance is sought to clarify the calculations and concepts necessary to solve the problem effectively.

I have this physics question i need help with.

An M gram chunk of hot iron is placed on a large piece of 0 degrees celsius ice, causing m grams of ice to melt.
a. What will be the final temperature of the system?
b. What must have been the initial temperature of the cold iron?
c. What must have been the initial temperature of the hot iron?
d.Calculate part c based on the following information M= 250g, m= 48g and the specific heat of iron = 0.44J / g degrees celsius

If someone has the answer thatd be great
Thanks

You must show some work to get help, we don't give out answers! What are your thoughts about it? What equations do you think you need?
 
need help actually

mc delta t (thermodynamics type)is all I've got and I don't know what to do with the two masses. I've been at it for a week and need a solution for friday morning.
 
I see only one piece of iron mentioned in the problem statement but two in the questions.

You need to find out about heat capacity, and the amount of heat required to melt ice.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
